If the AFCS is not awaiting EOM or continuation of mission (as in subsequent corrections then above UTE is sent. An example would be if the AFCS is waiting for the howitzer COS to depress the shot key.

HOWITZER MASK DATA (AFU;MASK):

"UTE-DD:HH:MM - MASK UPDATE DUE TO OVERLAPPING SEGMENTS IN DEFINITION."

The AFCS has request its last reported mask data from the BCS and the left and right azimuth limits overlap.

BCS has computed data and transmitted it to AFCS which is currently processing a priority target.

"UTE-DD:HH:MM - FM;COMNDS TARGET ID "TARGET NUMBER" DUE TO LAST MISSION REQUEST FOR THAT TARGET NOT COMPLETE."

BCS has sent FM:COMNDS requesting that AFCS to process however the AFCS is not a state with which it can process the mission. The howitzer COS has not depressed the "SHOT" and "ROUNDS COMPLETE" when prompted. The AFCS must be at awaiting end of mission or continuation of mission to process anything other than a priority mission.

HOW;OBSR sent with illegal projectile / fuze combination in SHAJ: or SHEF:.

The following messages are sent to the following devices, TFDMD, FIST DMD and ATHS:

FIRE REQUEST (FR;GRID):

"UTE-DD:HH:MM - COORD EXPANSION FAILURE."

a request for fire has been sent in short coordinates and either the observer failed to specify the use of "eastern" grid zone or the map model does not cover the requested area.

"UTE-DD:HH:MM - NO TARGET ID (TARGET NUMBER) AVAILABLE."

The AFCS cannot process the fire request due to all target numbers assigned by the HOW;OBSR message have been exhausted.

"UTE-DD:HH:MM - NOT ADJ PHASE PERMISSION."

The linked observer was not given adjust fire authority on the HOW:OBSR.

"UTE-DD:HH:MM - ALLOWED SH/FZ VIOLATION."

Linked observer requested an unauthorized shell / fuze combination.

"UTE-DD:HH:MM - FR;GRID IS IN CHECKFIRE."

a fire mission is sent while the AFCS in under checkfire.

"UTE-DD:HH:MM - TARGET ID (TARGET NUMBER)MUST BE GIVEN."

If the AFCS is in an active mission then the target number for that mission must be sent for any further processing.

"UTE-DD:HH:MM - BUSY WITH OTHER MISSION."

a request for fire is received, with a target number, however the target number does not match the current active mission.

"UTE-DD:HH:MM - BUSY LAST REQ FOR "TARGET NUMBER."

If the AFCS is not at the awaiting continuation of mission or end of mission state, then it will not process any other mission except priority.

"UTE-DD:HH:MM - NO ASSIGN PRI MISSION."

The linked observer does not have target storage permission.

"UTE-DD:HH:MM - PRI TGT ALREADY ASSIGNED."

a priority target already exists at the AFCS. This may have been assigned by the BCS or previously assigned by the linked observer. In any case the AFCS may only have one priority target.

SUBSEQUENT ADJUSTMENT (SUBQ ADJ):

"UTE-DD:HH:MM - SA EOM / EOM RAT NOT VALID."

The linked observer has attempted to end of mission or end of mission record as target with a subsequent adjust format.

"UTE-DD:HH:MM - SA IS IN CHECKFIRE."

The AFCS is in a checkfire state and any subsequent adjustment will not be processed.

"UTE-DD:HH:MM - SA "TARGET NUMBER" DUE TO NO MSN."

The linked observer has attempted subsequent adjustment on a non active mission.

"UTE-DD:HH:MM - SA BUSY WITH ANOTHER MISSION."

The linked observer has attempted subsequent adjustment with a target number which matches the current active mission however, the AFCS is not at an awaiting continuation of mission or end of mission state.

END OF MISSION AND SURVEILLANCE (EOM&SURV):

"UTE-DD:HH:MM - EOM TARGET ID REQUIRED."

The linked observer has attempted to end a mission without the active target number.

"UTE-DD:HH:MM - EOM "TARGET NUMBER" HAS NO ACTIVE MISSION."

The linked observer has requested end of mission on a target which is not active in the AFCS.

"UTE-DD:HH:MM - EOM "TARGET NUMBER" AS WRONG MISSION."

The linked observer has requested end of mission with the incorrect target number.

QUICK RESPONSE FIRE REQUEST (FR;QUICK):

DELETE:

"UTE-DD:HH:MM - DELETE TARGET ID NEEDED:"

The linked observer has requested the deletion of a target but no target number is given.

FIRE:

"UTE-DD:HH:MM - FIRE TGT IS IN CHECKFIRE."

a request to fire target number is received however, the AFCS is in a checkfire status.

"UTE-DD:HH:MM - FIRE TGT AS BUSY LAST REQ."

a request to fire target number is received and the AFCS is not at a AMC status.

"UTE-DD:HH:MM - FIRE TGT AS BUSY PRI MSN."

a priority mission is currently active and a request to fire stored target is received.

a stored TOT mission was activated automatically by AFCS however, the AFCS is processing a previously requested fire mission.

"UTE-DD:HH:MM - STORED TOT REQUEST TARGET ID "TARGET NUMBER" DUE TO LAST MISSION REQUEST FOR THAT TARGET NOT COMPLETE."

a stored TOT mission was activated automatically by AFCS and the TOT target number matched the current active mission. If the mission isn't awaiting end of mission or continuation of mission then it will be UTEed.

a cancel checkfire by target number was sent to AFCS however, the target number did not match. NOTE: a CANALL request will always match. Caution should be used when using CANALL as an undesired cancel checkfire may be sent.

a request to checkfire by target number is sent to AFCS however, AFCS is already in checkfire.

TARGET FILE STORAGE AND DELETION. The following messages apply to BCS and DMD type devices when a link has occurred. (NOTE: Only one subscriber may have target storage permission, either the BCS or DMD type device).

a fire mission message is sent to AFCS and the specified propellant is not in file.

"UTE-DD:HH:MM - SPECIFIED FUZE "FUZE MODEL" NOT IN AFCS INVENTORY."

a fire mission message is sent to AFCS and the requested elements do not match what is in the AFCS ammunition inventory.

"UTE-DD:HH:MM - ILLEGAL PROJECTILE, PROPELLANT, FUZE COMBINATION."

a fire mission message is sent to the AFCS and the request contains illegal combinations for ammunition, propellant, and fuze.

"UTE-DD:HH:MM - INSUFFICIENT AMMUNITION."

a fire mission message is sent to the AFCS and the howitzer COS was prompted that the requested quantity of ammunition is not on hand. If the COS denies the mission for the above reason, then the above UTE is sent to the BCS.

When the AFCS receives a fire mission message and more than one of the specified elements is not in file, one of the following UTE messages is sent:

a fire mission message is sent to the AFCS and the maximum range of the propellant is compared to the range to the target. If the target range exceeds 85% of that for the propellant (90% for high angel fire) the above UTE is sent to the BCS.

FUZE SELECTION:

"UTE-DD:HH:MM - BECAUSE "FUZE TYPE" NOT IN INVENTORY."

a fire mission message is sent to the AFCS however, no legal fuze is found.

"UTE-DD:HH:MM - NO LEGAL AMMUNITION COMBINATIONS INVENTORY."

a fire mission message is sent tot he AFCS however, the AFCS found no legal combinations for projectile, powder, and fuze.

CHARGE SELECTION:

"UTE-DD:HH:MM - EXCESSIVE RANGE TO TARGET."

a fire mission message is sent to AFCS and the target range exceeded 85% of the range of the powder model (90% for high angle fire).
